COOKS ILLUSTRATED BLUEBERRY SCONES PART 1

Steps:

• 1. Heat oven to 425 degrees. Score and remove half of wrapper from each stick of frozen butter. Grate unwrapped ends on large holes of box grater (you should grate total of 8 tablespoons). Freeze grated butter until needed. Melt 2T of remaining ungrated butter and set aside. Place blueberries in freezer until needed. 2. Whisk together milk and sour cream in medium bowl; refrigerate until needed. Whisk flour, 1/2 cup sugar, b/powder, b/soda, salt, and lemon zest in medium bowl. Add frozen butter to flour mixture and toss with fingers until thoroughly coated. 3. Add milk mixture to flour mixture; fold with spatula until just combined. With rubber spatula, transfer dough to liberally floured work surface. Dust surface of dough with flour; with floured hands, knead dough 6 to 8 times, until it just holds together in ragged ball, adding flour as needed to prevent sticking. 4. Roll dough into aprox 12-inch square. Following illustrations, fold dough into thirds like a business letter, using bench scraper or metal spatula to release dough if it sticks to countertop. Lift short ends of dough and fold into thirds again to form approximate 4-inch square. Transfer dough to plate lightly dusted with flour and chill in freezer 5 minutes. see Cooks Illustrated Blueberry Scones Recipe Part 2
